Some seats may require the removal of hinge covers to access the hinge mounting holes.Place each washer over the toilet seat hinge mounting holes, and insert the compression bolts into the washer-hinge-gasket bolt holes.Thread the bolts into the gasket bushings, starting by hand to prevent misalignment and crossthreading of the fasteners.Doublecheck toilet seat placement and alignment with the base toilet fixture.

Caution: the use of power tools is not advised, and may cause overtightening, injury or damage to the fixture.If toilet seat hinge covers were removed for installation, reinstall the covers.

Review: These work! - These work VERY well. Had them installed in one bathroom for over a year and the seat has remained exactly where it needs to be.
Review: Effective Replacement for Toto - This worked great for my Toto toilet. Be careful when putting them in, they can fall in (why I ended up ordering these in the first place). Fit perfectly and toilet seat doesn't wiggle around, seems sturdy enough.

### ⭐⭐⭐⭐⭐ These work!
*by R***H on November 22, 2025*

These work VERY well. Had them installed in one bathroom for over a year and the seat has remained exactly where it needs to be.

### ⭐⭐⭐⭐⭐ Effective Replacement for Toto
*by R***R on May 28, 2025*

This worked great for my Toto toilet. Be careful when putting them in, they can fall in (why I ended up ordering these in the first place). Fit perfectly and toilet seat doesn't wiggle around, seems sturdy enough.

### ⭐⭐⭐⭐⭐ Works as advertised!!!
*by T***P on November 11, 2024*

Ease of installation, but used soapy water as lubrication & a pair of plier to pull it through the hole. I replaced our Toto’s toilet seat two years ago, but it wiggled no matter what I did to tighten the mounting hardware. This quickly resolved that issue and I think it is worth the price.
